Spark

Apache Spark is a multi-language engine for executing data engineering, data science, and machine learning on single-node machines or clusters.

Spark handles massive workloads by processing data in-memory, delivering speeds up to 100x faster than traditional MapReduce. It supports SQL queries, streaming data, and complex analytics through libraries like MLlib and GraphX. Engineers use it to manage petabytes of data across thousands of nodes (nodes are the physical or virtual machines in a cluster). With native support for Python, Scala, Java, and R, it remains the gold standard for unified batch and real-time processing.
